Fueling Primary open loop

i have a subaru sti 2016 and in the stock map , the primary look open fueling as you instruct in the video to select that one is not there only the primary loop fueling (fail safe), what choices i have to be able to start to to tune the stock map , all i have in the fueling section is

primary open loop fueling KCA ADDITIVE B LOW , KCB ADDITIVE B HIGH , alternate mode , faisafe kca alternate mode , fuel map switch IAM ,

the others are Minimun active primary open loop enrichment , primary open loop enrichment throttle , accelerator , fuel compensation ECT , and timing compensation , that's all , any help woul be appreciated

thanks

If I recall correctly, it would be KCA ADDITIVE B HIGH and LOW table that are used in normal condition, and the failsafe is used when the IAM get below the MAP SWITCH value.

Thanks for responding and sharing , so that means i can work in the B high first and interpolate all the arrange from B high to the low table or start with the low first ?

If I recall correctly, both tables have the same values. Each time you do a change, they should always match (copy - paste your change in both of them).

Thanks a lot frank , appreciate will try that lets see how it goes

Can someone explain the KCA Additive B Low and High tables? I have a 2014 STI and with stock map, the KCA high and low tables don't match. Are they supposed to match to start? I assume with AFR tuning, we make these tables equal because we are using the external AFR to calibrate the MAF?

Both Failsafe and Failsafe KCA Alternative modes are the same for me. I also see Primary Open Loop Fueling KCA Alternative mode. This table has completely different values. How should I interact w/ the KCA Alternative Mode, KCA Low and KCA High tables?
